Parts for your 2015 Subaru Outback-Control arms

2015 Subaru Outback Control Arms

Control arms are absolutely fitted to the 2015 Subaru Outback (BS series). Technical references that confirm this include the Subaru Service Manual for 2015 Outback/Legacy (Front and Rear Suspension sections), the Subaru parts catalogue (which lists front lower control arms and rear lateral/trailing links), and common aftermarket catalogues that supply complete arms, bushes and ball joints for this model. So yes—control arms are relevant to this vehicle.

On the front, the Outback uses a MacPherson strut with a lower control arm that locates the wheel hub and manages camber and caster through its bushes and ball joint. Down the back, the multi-link setup uses several arms (often called lateral links and a trailing arm) that do the same core job—keeping alignment steady while the suspension moves. Depending on variant, the front lower arms may be steel or alloy, but the function is the same: connect the wheel to the subframe, control geometry, and help the car steer and brake straight.

Fresh bushes and a tight ball joint keep the steering crisp and protect tyres from scrub. When the bushes crack or the ball joint loosens up, drivers may notice clunks over bumps, vague steering, a pull under braking, or uneven tyre wear. Coastal exposure, corrugations, and big kilometres around Australia and New Zealand can speed up wear.

• Inspection: Every 20,000–30,000 km, check front control arm bushes for splits, oil swell, or tearing, and feel for play at the ball joint. Look for bent arms after a pothole hit.
• Replacement: If one front arm is shot, it’s smart to replace in pairs. Choose complete arms (with pre-fitted bushes/ball joint) for convenience, or press-in bushes/ball joint if you prefer OE arms.
• Fitment tips: Torque pivot bolts at normal ride height so new bushes aren’t preloaded. Replace any single-use/stretch hardware as specified by Subaru. Always follow service manual torque specs.
• Aftercare: Book a four-wheel alignment straight after—camber, caster and toe can all shift when arms or bushes are changed. Re-check fasteners after a few hundred kilometres on rough roads.

A tidy, quiet front end isn’t just about comfort, it’s a safety and compliance issue too. Worn control arm bushes or ball joints can knock a WOF or RWC back, and they’ll chew through tyres. Sorting them early keeps the Outback feeling planted and predictable.

Popular questions about 2015 Subaru Outback control arms

Does the 2015 Outback have rear control arms?
Yes. The rear suspension is a multi-link arrangement that uses several arms—commonly called lateral links and a trailing arm—to control wheel position. Many parts guides group these under “rear control arms”. Their bushes can wear and affect alignment, so they’re checked during servicing and alignments.

How long do control arm bushes last on a 2015 Outback?
It varies with use and environment, but 80,000–150,000 km is typical. Lots of gravel, heavy loads, or coastal salt can shorten life. Tell-tales include clunks, vague steering, instability under braking, and feathered or rapidly wearing tyres.

Do I need an alignment after replacing control arms?
Definitely. Changing arms, bushes or a ball joint alters geometry. A proper four-wheel alignment restores camber, caster and toe so it drives straight and protects your tyres. If the subframe is shifted during repairs, alignment is even more critical.
